What is a key transmission method of Platynosomum concinnum?

• A. Ingestion of contaminated water
• B. Ingestion of lizards or frogs
• C. Direct skin contact with infected animals
• D. Airborne transmission

Answer: (B)

Platynosomum concinnum, commonly known as the cat liver fluke, primarily utilizes lizards or frogs as a critical transmission method within its lifecycle. Cats become infected when they ingest these intermediate hosts, which contain larval forms of the parasite. The life cycle of Platynosomum concinnum involves freshwater snails as the first intermediate host, but the definitive method of transmission to felines occurs through the consumption of infected reptiles. Other options present alternative methods of transmission that do not pertain to the life cycle of this specific parasite. For instance, contaminated water or airborne transmission does not facilitate the lifecycle of Platynosomum concinnum, nor is direct skin contact relevant. Understanding the life cycle and transmission of specific parasites is essential for effective veterinary practice, particularly in understanding preventive measures and controlling infections in pets.
